Shape is similar. Anything is possible, but the movements they made are not something any known aircraft can do, he described their movements, saying that they flew “like a saucer if you skip it across the water.” " the entire assemblage "stretched out over a distance that he later calculated to be five miles." The objects seemed to be flying on a single, horizontal plane, but they also weaved from side to side, occasionally flipping and banking—darting around, Arnold would say, like “the tail of a Chinese kite.” They moved in unison, Arnold said. They didn't seem to be piloted, he said. Once Arnold realized the objects were not, in fact, commercial jets—or, as he’d also thought for a moment, a skein of geese—he figured he was witnessing the testing of military aircraft.
